Application filed J'une 3, 1918. SerialNo. 237,875. I

To all whom z't may concern.-

Be-it known that I, CALVIN C. CAVANAGH, aoitizen of theUnited States of America, and resident of Beverly, in the county of Essex and State of Massachusetts, have invented new and usefullmprovements :in Window-Closures, of which the-following is a specification.

This inventionrelates to doorand window closures and more particularly to a weather strip. Theprincipal object of the invention is to provide means for positively and ef fectually closing the crack at the bottom of a, door or window againstwind, rain and insects. A secondary object is to provide means, adapted to. lock a door or window closed as well as to function as a'weather strip. Another object ofthe invention is to provide means for automatically moving theweather-strip into operative or inoperative position when. the door .is a closed ..or open. 7

The-present invention, is applicable either t0 a window 012a door; and I have therefore .Shown'the inventioningFig. 1 as applied to dou e-fl ors. offlt e F ench W n p VlT-ith;thisftype of door I may also illustrate; the manner.. in which the ,,mechanism maybe operated either 1 automatically or mechanically.

TheHinQQ-WS I. endDfarehingeclto the casing members 3 and 4 (Fig. 2) by means of hinges 5 and 6 so as to swing over the $111 7 into the position shown in Figs. 3 and 4 when closed. As is customary, the wlndow D is provided with a flange or stop 8 against which the window D abuts when closed, the window D being fastened in closed position in any suitable manner-and the window D being held in closed position by means of a latch connection with window D (not shown). .I have illustrated the manual embodiment of my invention-as applied to window D and the automatic embodlment-of the invention as applied to window D. Inasmuch as certain features of construction are common to both the manual and automatic embodiments of the invention I will first describe these common features.

In a recess 9 (Figs. 5 nd 6) at the bottom.

of each window is pivotally mounted the closure means C. The preferred construction of the closure means C comprises a bar 11 provided at its opposite ends with trunnions 12 and 13-adapted to be journaled in plates 14 and 15 set into the lateral edges of the door at the bottom of the door. The bar 11 is preferably made in two portions adjustably connected together by a screw and slot connection, as illustrated in Fig. 7, so-that the distance between the trunnions 12 and13 may be varied to adjust the mechanism to a door and to adjust for shrinkage or expansion of the door. A spring 16 is preferably provided around one of the trunnions between'the end of the bar and the end plate to prevent endwise movement of the In the preferred embodiment the closing strip proper is comprised as follows: The central portion, of the strip is fastened to the upper side of the bar 11 by means of a row of screws 18, the forward-portion 17 of the strip being'bent over the forward edge of the bar 11 and extending beyond the lower side of the: bar' in perpendicular relationship to its lower face. The rear end 20 of the strip is bent outwardly from the bar so as toextend'into juxtaposition to the wall of the'recess 9 when the mechanism is in the operative position shown for example 'in Fig.5. When the strip is in operative posi tion the forward portion :17 liesalong the shoulder 21on the 'sill 7 and the rearpo'rtion 20 extends into juxtaposition to the wall of the recess 9 so that the space between the window and the sillis effectually closed against wind, rain and insects When the device is in this position the window which opens to the left, as indicated 1n Flgs. 3,

4, and 5 by the arrows, cannot be openedin asmuch as the strip extends in behind the shoulder 21. In order to open the window it is necessary to swing the strip into the inoperative position shown in Fig. 6' where the forward portion17 of the strip is w1thdrawn wholly within the recess inv the window.

The manual means for actuating the closure mechanism C is illustrated in detail in Figs. 3. and 4. The closure means C as applied to the window D in Figs. 1 to 4 is ournaled at its opposite ends in plates 22 to 23 corresponding to plates 14 and, 15 on window D in Figs. 1 and 7. On the inside of plate 22 a lever 24 is pivotally mounted on a pin 25 so that the. lower end of the arm extends into juxtaposition to the strip 17 The arm 24 is provided with a flat face 26 adapted to rest squarely against the strip 17 when the strip is in inoperative position, as shown in Fig. 3, and adapted to serve as a cam face to swing the closure means C from inoperative position shown in Fig. 3

- to the operative position shown in Fig.4

when the arm is swung in aclockwise direction from the position shown in F ig. 3 tothe positionshown in Fig. 4. ,A screw 27 extends through a slot 28 in strip 17 such as shown at 28 in Fig. 7, and thence intothe lower end of arm 24. A tension spring 28 extending between pin 29 and screw 30 tends to throw the arm24 into the inoperative position shown in Fig. 3. When the arm is thrown to the left by spring 28 the closure means C is swung into inoperative position by the head of the screw 27 engaging the under side of the strip 17. The manual means for controlling the arm 24 comprises a lever 31 pivotally mounted on pin 32, the lever 31 being provided'on its inner end with a cam surface 33 for engaging a cooperating surface on arm 24 and being provided on its outer end with a ring 34 disposed outside of the window. These cam surfaces are so shaped that the arm 24 is locked in each of its positions by means of the lever 31 so that the window can only be opened after the lever 31 has been moved down into the position shown in Fig. 3. A plate 35 is provided to close the forward side of the chamber containing" the actuating mechanism, this member being secured to the window bymeans of screws 37 and being provided with a slot 38 to permit the arm 31 to extend outside the casing. The end plate 22 upon which the actuating mechanism is mounted is secured to the window by means of two screws 39. The automatic embodiment of my inventionis illustrated in detail in Figs. 8 to 10.

The closure means 0 is constructed as above described and cooperates with a shoulder on the window sill as in Figs. 3 and 4. The actuating arm' 24 corresponding to arm 24 in Figs 3 and 4 is pivotally mounted by means of a pin 25 as in Figs. 3 and 4 but the pivot pin is disposed fartherto theleft and the lower end of the arm is provided with a circular projection 40 extending outwardly through a slot in the flange 41 extending at right'angles from the plate 15 along the inside of the window D. The arm 24 is controlled by a spring 28 as in Figs. 3 and 4. The circular, projection 40 extends from the window D at such a point that it will engage the lower end of the flange 8 (Fig. 2) of the window D when the window D is closed and when thus engaged is forced inwardly,-throwing the parts into the position shown in Fig l0 with the strip 17v in 1 position behind the shoulder in the window sill. In order to prevent undue wear on the window D by the projection 40 I preferably provide a metal plate 42. A reinforcing member 43 may be provided to strengthen the strip 17 around the slot 28, (see Figs. 7, 8, and 9). j

When applying the manual and automatic embodiments of my invention to French windows the manual means is preferably associated with the window which is used least and the automatic means with the window which is used most. The manual means may be employed alone to maintain the one window locked in closed position or itmay with a single door or window, and when used with a single door or window the projection 40 of the automatic means would engage the door or window casing.

By virtue of my invention the space between the door and casings is tightly closed, but unlikeother weather strip mechanism in no wise interferes with the opening and closing of the door or window- I I e The words bottom, horizontal, vertical etc., as used in the claims, are used in the relative sense to define relative relations and positions and not in the absolute sense. Thus the claims are intended to cover the application of applicants improved weather strip to the side or top of a door or window as well as the bottom.

I claim: 4 l 1 1. A door having a recess in the bottom thereof, and a weather strip substantially wholly disposed withinsaid recess in its Y pivoted at its remoteedge and projecting.

at approximately right angles to said strip so that when the bar is horizontal the strip stands substantially vertical in position to engage behind a substantially vertical shoulder on the sill.

2. A door having a recess in the bottom thereof, and a weather strip substantially wholly disposed within said recess in its inoperative position and between the planes of the faces of the door in its operative position, said weather strip comprising a flexible packing strip and a rigid carrying bar secured to the edge of the strip and pivoted at its remote edge and projecting at approximately right angles to said strip so that when the bar is horizontal the strip stands substantially vertical in position to engage behind a substantially vertical shoulder on the sill, and a pivoted device engaging the flexible part of said strip to force the same downwardly past and then toward the shoulder on the sill.

3. A door having a recess in the bottom thereof, and a weather strip substantially wholly disposed within said recess in its inoperative position and between the planes of the faces of the door in its operative position, said weather strip comprising a flexible packing strip and a rigid carrying bar secured to the edge of the strip and pivoted at its remote edge and projecting at approximately right angles to said strip so that when the bar'is horizontal the strip stands substantially vertical in position to engage behind a substantially vertical shoulder on the sill, and a pivoted device engaged by the closing of the door engaging the flexible part of said strip to force the same downwardly past and then toward the shoulder on the sill.

4:. A door having a recess in the bottom thereof, and a weather strip substantially wholly disposed within said recess in its inoperative position and between the planes of the faces of the door in its operative position, said weather strip. comprising a flexible packing strip and a rigid carrying bar secured to the edge of the strip and pivoted at its remote edge and projecting at approximately right angles to said strip so that when the bar is horizontal the strip stands substantially vertical in position to engage behind a substantially vertical shoulder on the sill, and a pivoted device engaging the flexible part of said strip to force the same downwardly past and then toward the shoulder on the sill, said pivoted device having a lost motion connection with said strip so that the device may withdraw the same by a vertical motion as well as press same toward said shoulder, and means for givin such return motion to the lever.
